2 / 20 page TPA6102A2 50mW ULTRALOW VOLTAGE, FIXEDGAIN STEREO HEADPHONE AUDIO POWER AMPLIFIER SLOS324B − JUNE 2000 − REVISED SEPTEMBER 2004 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 AVAILABLE OPTIONS TA PACKAGED DEVICE MSOP TA SMALL OUTLINE (D) MSOP (DGK) MSOP SYMBOLIZATION −40 °C to 85°C TPA6102A2D TPA6102A2DGK AJN Terminal Functions TERMINAL I/O DESCRIPTION NAME NO. I/O DESCRIPTION BYPASS 1 I Tap to voltage divider for internal mid-supply bias supply. BYPASS is set at VDD/4. Connect to a 0.1-µF to 1-µF low ESR capacitor for best performance. GND 2 I GND is the ground connection. IN1− 8 I IN1− is the inverting input for channel 1. IN2− 4 I IN2− is the inverting input for channel 2. SHUTDOWN 3 I Active-low input. When held low, the device is placed in a low supply current mode. VDD 6 I VDD is the supply voltage terminal. VO1 7 O VO1 is the audio output for channel 1. VO2 5 O VO2 is the audio output for channel 2. absolute maximum ratings over operating free-air temperature (unless otherwise noted)† Supply voltage, VDD 4 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
